Description

Field of the Invention The present invention relates to a fixed connector, and more particularly to a multiple airtight, waterproof, anti-strain cable fixed connector that can provide multiple protection and multiple packing sealing actions for cables.

Electrical cables are usually used in electrical boxes, equipment and telegraphs, network communication boxes, etc., the electrical cable is easy to be pulled under external force, the connection position of the fixed head is easy to loosen, displace, fall off, and the water is It is easy to create a situation where the electrical box or equipment or telegraph, network communication box is flooded along the cable.

Therefore, manufacturers are researching and developing fixing connectors that can be used to fix cables, such as ROC Patent No. 338572 "Improvement of cable fixing head", No. M357111 "Waterproof and anti-stretch cable connector". No. M391223 "Cable fixing head with waterproof ring", No. M393906 "Double-packing waterproof fixing head for cable and corrugated tube", the existing structure consists of connecting ring, clamping claw, packing ring. , has an outer cover, in which the connecting ring is used to fix a predetermined object, such as a machine board, the connecting ring is screwed with the outer cover, and the clamping claw is integrated with the packing ring. It is covered and installed in the outer cover, which uses the outer cover to press the clamping claws and the packing ring, causing them to deform and form a clamping and tightening effect on the cable wire, and using this clamping and tightening effect. and achieve the purpose of fixing electric cables and waterproofing at the same time.

However, from the outside, the above existing structure has at most a connecting ring and an outer cover to protect the electric cable on the outside, and the inside has at most only one packing ring to protect the electric cable. Only clamping, that is, it only has a single clamping action, and can only perform a single orientation for the electric cable, thus the above existing structure has multiple protective actions. It does not have multiple clamping action, the electrical cable cannot be efficiently secured with better protection, and besides having the instability that the electrical cable is only single-fixed, its Electric cables are also easy to pull and fall off, and the waterproofness of this kind of structure is not good.

In the two existing structures of the above No. M391223 "Cable fixing head with waterproof ring" and No. M393906 "Double-packing waterproof fixing head for cable and wave tube", the packing ring consists of a first packing part, a second packing The parts tightly clamp the corrugated tube and the electric cable, respectively, to achieve the effect of double packing, provided that the first packing part and the second packing part are integrally formed instead of being formed on the two packing rings respectively. Formed on one packing ring, which is connected to each other in an integral structure, when it is pulled and loosened under the action of an external force of one of the corrugated tube and the electric cable, the first packing part and the second packing part usually It simultaneously affects the clamping action of the two packing parts and, in effect, has only a single clamping action.

In addition, the above existing structures need to have a higher IP (INTERNATION PROTECTION) value when used in dynamic machinery, outdoor environments that are subject to strong winds, deep water environments, and high explosive gas environments. However, based on the above existing structure, it only has a single electrical cable clamping action, which cannot be applied to dynamic machinery and the above environment, and has poor practicability.

Synthesizing the above description, any electrical box shell can only install one cable fixation connector for the same electrical cable in the hole through which one cable exits, but one existing cable fixation Due to its limitations, the connector can only accommodate one set of fixing members, and one set of fixing members can only perform one set of "airtight" and "waterproof" and "anti-stretch" functions. is.
